freelance, do you mind sharing what you DID eat for the rest of the day and whether or not it filled you up? Do you feel that you could have eaten that same meal for lunch and dinner? If so, then no doubt the practice of IE would probably result in some weight gain for you. So if that is what your body is telling you and you are not willing to take that chance, you are smart to stay on your current plan.

I don't remember everything I ate that day after the big breakfast, but I know it was quite a bit: a quesadilla and a large carrot-zucchini muffin for lunch and a normal supper of some kind, along with wine. I had lunch at noon, right after my run, and was definitely hungry for it -- even after that 1,000-cal breakfast.

As I've mentioned before, I was born with a large appetite, weak fullness signals, and an iron stomach. So yeah, IE would surely result in weight gain for me.
